To all whom it may concern.:

Be it known that I, BRYANT B. Envianos,

citizen'l of the United States, residing at Berkeley; in the county 'ofAlameda and State of California, have invented new and useful4Improvements in Tater-Heaters, of which the following is aspecification.'

My invention relates to Water-heaters, and pertains more particularly toinstantaneous, automatically controlled gas water-heaters. It is anobject of this invention to provide a means wherebya Siiglelieater'ofthis class may beein loy`ed to supply heated water to several inependent l points'of distribution, in combination with .means forproperly reg istering' the amount of .water drawn and gas consumed byAtheindependent party service, or at point of distribution, so that thecorreci. charges'inay bemadeagainst eachindividual consumer.. v

The invention consistsof .the elements, the

construction and combination of elements, or

their equivalents, and willV be,v clearly s'et forth in the followingspecification, and acis a side elevation o companying drawin" inwhicli'fthe figure glie device.-

^ 1 In this class of apparatus, a heater .of suiti able constructionisemployed having an inlet for cold water, eirculatingrcoils anda`hotwater outlet; a. ,fs'uitalile burner issupplied with fuelromffasource of supply, the fuel bein usually automatically controlled,and

ivhic is' ignited by the customary pilot,- ilight.

4In the embodiment of my invention as actually reduced to practice, vIuse a heater 2 of any desirable construction, in the lower art of whichis mounted aga-s or other urner 3, sup lied with fuel through aVconnection 4 with the manifold 5. A series of coils 6 are inter osed.above the burner 3,' and cold water is le in from the up r manifold,would 7, and passes outheated near t e bottom of the heater into a head8.

For the purpose of providing an apparatus 'that-is adapted to furnishheated water to a pluralit ofA independent systems, such as be requirein av large apartmenthouse, or to several distinct consumers,it'isnecessarv that the water delivered into the 7 shall be registered toeach consumer using it, and that the amount he uses,

and no more, be properly recorded. To accomplish this,su1tab emechanical orother means 4must be ern loyed whereby the open-v ingof anydraw-o faucet in a given service secu re mat-ically operate to open aspring-actuated sup ly control valve,'such as at 9, to admit col waterthrough its respective inlet ipe 10 into the common manifold 7. Thereore, each hot water service ipe l1, leading from the head 8, is provide/with a valve 12 of suitable character, but here shown as a pis'-ton-valve, the water passing from the pipe 11 tothe top of the piston13, andwhen the faucet 14 is opened', the waterpressure drives thepiston 13'down, and a chain or wire 15 connecting the piston 13, and alever 16, serves to open supply valve -9 to which ,water passes aftergoing through a meter 18. It is thus manifest that no water can `passthrough meter 18, Aor valve, unless the pressure below the piston 13 isrelieved by openin thus a owing the piston 13 to descen open the v'alve9.

The valve 9 and piston 13 are cach provided with asmall by-pass 17. and19, respectively, for theequalization ofpressure ,and in order to insurea ainst accidental operation-of valve 12, a c eck valve is interposedbetweenV it and the :heater 2.,; Vliile I havedescribed the operationand construction of a single Sivice -systein connected tothe head 8, andmanifold ff, a plurality of systems may be supplied, is shown by theinlet pipes 10, and out et pipes 11.

Each stein isy individually co'iinected to the mani old 5 by a gas suply pipe 21, leading from meter 22 to a va ve 23, which may be opened onthe downward stroke ofifpiston 13 and rod 24. When the piston descendsandopcns valve 23, gas passes throughs. valve at 25, ivh-ichis closableby a thermostat 2G interposed in the length of delivery pipe 11, undeffective to close valve 25 when' the water has reached a predeterminedteinperature. It will now be seen that no gas can flow to the manifold5,'and thence to the burner 3, and that no water will pass to themanifold 7 until some faucet, such as 14, is opened to permit the piston13 to' descend and -open valveA 9 against its spring, and also to openthe gas valve 23.

The usual pilot light supply 27 leads from the upper part of thegast-valve 28 and is and as many pilot lights as 'there are independentservice systems.

This construction provides a perfectlyK au a faucet 14 in theservicepipe 11,

adjacent the burner; 3, there may be pipe 11, leading from the head 8,will autoi i'io tomatic heater adapted to serve severaldistinct'parties, and provides for the accurate and independentrecording of material consumed by each. i

This specification and; the drawings'set .forth one simple arrangementfor the aceomplishment of the functions of the invention,

principles involved.

.The port 17 in the amount of supply to disturb the equilibrium whensaid source is opened, and as this port is slightly larger than the port19 in the `piston 13,

valve 9 allows a: small this result will follow: When the discharge Vcock isclosed equilibrium within the appa- 20 ,Spring foonteinp 2 5 iratus is restored through theopening 19 in :the piston, and the returnof the piston and its connected parts is insured by means ofja 19a.A l

It .will be understood-1 that a single'pilot light might be used, butthe present dewce ates such a light for eachzseparate service, so thatalthough only using a v ery small quantityof gas, that vamount will be:

properly` divided among thecOnSumers.
